Riciclare il polistirolo

20 Marzo 2018
Dagli imballaggi alle tazze da caffè monouso, ogni anno gli Stati Uniti producono da soli circa un milione di tonnellate (907.180.000 kg) di polistirolo - nessuna delle quali può essere riciclata. Frustrato da questo spreco di risorse e di spazio per le discariche, Ashton Cofer e i suoi compagni di scienze hanno sviluppato un metodo di riscaldamento per trasformare il polistirolo usato in qualcosa di utile. Date un'occhiata al suo originale progetto, che ha vinto il premio Scientific American Innovator alla Google Science Fair.
